On the contrary, they're still very traditional people, I mean for god sakes, they still use faxes and prefer paperwork stacks to computer files.
This is just anime, which is also uncommon for most Japanese people, since people who regularly watch anime are called "Otaku" or outsider in English, these people are then heavily shunned, and Otaku are considered a great shame to the family name.

To start, let's talk a little about Japanese TV. You may have seen clips of some X-rated Japanese game show floating around the Internet wherein an audience full of young women eagerly compete for the privilege of having sex with some random guy on stage in front of hundreds of people (if not, you're probably searching for them right now). Here's the shocking truth behind those videos -- they are porn.

After all these years in Japan, I can honestly say that animation (major studio productions notwithstanding) is still mainly considered kids' stuff. There is shockingly little anime on television, and most of it is unapologetically meant for children. The only adults who really get into it (referred to as otaku) are usually perceived by the media as overweight, unwashed weirdos who are probably child molesters. Sound familiar? You're bound to spend just as much time hiding your Trigun DVDs from company here as you would anywhere else.
